3-27 <br />STATION 42+00 <br />i <br />This area on the road was chosen to analyze for stability because it is one of the steepest <br />portions of the road. The area has a history of surface sloughage throughout the life of the <br />road, but has not had any major slope failures. Unlike the previous area, this area has highly <br />cohesive soils that enhance the stability of the slope. Analysis of the present configuration <br />indicates a factor of safety of 1.305. The reclaimed configuration using a moderately cohesive <br />soil, 300 psf, shows a stable factor of safety of 1.317. Once again, analysis of just the backfill <br />was performed indicating a factor of safety 1.969. This slope should be stable after it is <br />reclaimed as shown on Fgure 3.1.6. <br />STATION 47+00 <br />The next slope analyzed for stability is located just below the mine site as shown on Fgure <br />3.1.4. The area has also had a history of surface sloughage and has highly cohesive soil. The <br />cohesive soil contributes to a factor of safety of 1.363 for the present configuration , 1.370 for <br />• the reclaimed configuration, and 1.760 for the backfill. The analysis indicates that the <br />reclamation proposed will be stable. <br /> <br />M~ Volume I 12 - 18 - 96 <br />
